REINFORCING METAL YOKE FOR HOLLOI/V CONCRETE WALLS.

To all whom it may concern:

Be it known that I, IVILLIAM E. NELSON, a citizen of the United States,residing at San Angelo, in the county of Tom Green and State of Texas,have invented certain new and useful Improvements in Reinforcing MetalYokes for Hollow Concrete Walls, of which the following is aspecification.

My invention relates to reinforcing means for walls formed of plasticcomposition, and which are molded in successive vertical sec tions.

An object of my invention is to provide reinforcing means for hollowplastic walls, which are adapted to unite transversely the two sides ofthe hollow walls and to vertically support the same.

A further object of my invention is to provide reinforcing means forhollow plastic walls, which consist of frames embedded within the same,connecting transversely the two sides and supporting the downwardpressure of the same and reinforcing said wall longitudinally.

A further object of my invention is to provide reinforcing means of thecharacter described, by the use of which the housing generally employedin the building of plastic walls may be done away with.

In the accompanying drawings illustrating the preferred embodiment of myinvention and in which like numeral references designate like partsthroughout the same, Figure 1 is a cross sectional view of a hollowconcrete wall, and mold therefor, showing my reinforcing means arrangedtherein. Fig. 2 is a perspective view of one of my yokes. Fig. 3 is afragmentary perspective view of a modified form of the yoke shown inFig. 2. Fig. 4 is a fragmentary perspective view of a bracket forsupporting a brick wall upon the side of the concrete wall and showingmeans adapted to embrace one of the yokes and support the bracket. Fig.5 is a fragmentary view of a plurality of my yokes and showing asectional view of an I-beam arranged between and secured to the same.Fig. 6 isa perspective view of my reinforcing frame consisting of yokesconnected by strips. Fig. 7 is a side view partly in section of aslightly modified form of my yokes shown in Figs. 1 and 6, and showingthe horizontal bars arranged thereon. Fig. 8 is a cross sectional viewtaken on the line 88 of Fig. 7. Fig. 9 is a perspective view of one ofthe hori- Specification of Letters Patent.

Patented Apr. 12, 1910. Serial No. 502,644.

zontal rods shown in Figs. 7 and 8. Fig. 10 is a perspective view of aplurality of my yokes of a modified form different from the yokes shownin Figs. 1, 2, 3, 6, 7 and 8.

In the drawings, 1 designates the base of a yoke having the upwardlyextending and outwardly spreading arms 2 and 3, and said yoke may bemade of either cast, wrought iron or steel. As shown in the drawings,the arms 2 and 3 join the base 1 within its outer extremities, except inthe modified form shown in Fig. 10, wherein the sides 2 and 3 join thebase 1 at its extremities. The upstanding sides 2 and 3 spread outwardlyfor a purpose hereinafter described.

The extremities of the upper face of the base of my yokes, except in thecase of the form shown in Fig. 10, are beveled inwardly as shown at 4,to provide a catch for the inwardly turned and upwardly beveled ends 5carried by the arms 2 and 3.

It will be apparent that when the base 1 of a yoke, except in the caseof the form shown in Fig. 10, is placed transversely between the arms 2and 3 and in engagement with the extremities 5, the said base 1 cannotbe forced downwardly unless the said sides 2 and 3 spread and this isprevented by the upwardly beveled extremities of the base 1 and sides 2and 3 in engage ment with each other. Thus a chain may be formed of theyokes capable of supporting vertical pressure. It is often desirable tosustain the downward pressure of the wall between the chains of yokes,and to accomplish this end I secure the strips 5 upon the arms 2 and 3of the yokes as shown in Fig. 6, by bolts 6 or the like. By thisconstruction a frame-work is obtained which will sustain the downwardpressure of the sides of the wall and connect the same transversely.Instead of the strips 5, I may employ rods 7 provided with the hookedends 8. The rods 7 are especially adapted to be applied to the form ofmy yokes shown in Fig. 7. In this figure the hooked ends 8 are shownfitting over the base 1 of the yoke. In Fig. 8 the application of therods 7 is very clear, the hooked ends 8 of the rods 7 extending inopposite directions engaging opposite sides of the base of the yoke.Thus chains composed of the yokes shown in Fig. 7 may be united to forma frame similar to the frame shown in Fig. 6.

The yokes shown in Fig. 10 are intended to be used in walls which arenot subjected to very great pressure. These yokes are socured to eachother as shown in Fig. 10, by the bolts 8 which pass through the upperand lower extremities of the sides 2 and 3 of each yoke and which securethe upper extremity of one yoke to the lower extremity of acorresponding yoke. These yokes may thus be made into chains, which areadapted to vertically support the sides of a hollow wall and connect thesaid sides transversely.

lVhen constructing a concrete wall, the yokes are set transverselywithin a mold form 6, resting upon the foundation or as illustrated inFig. 1 upon a previously finished section of the wall 7, the said yokesbeing locked to the corresponding yokes embedded within the finishedsection and extending upwardly therebeyond. The plastic composition isthen filled in the mold between its inner and outer walls, thusembedding the yokes and the strips secured thereto within the same.

If it should be desired to transfer directly the support of the floor orceiling to the reinforcing means of the walls, the chains composed ofthe yokes before described, may be suitably spaced apart, and the I-beam13 arranged between the same and secured to the arms 2 and 3 by means ofthe bolts 1% as shown in Fig. 5.

If it should be desired to build a brick wall 8 or other facing alongthe side of the concrete wall and have the said brick wall supported bythe concrete wall, I provide a bracket 9 having the opening 10 and thedepending tongue 11 therein. 1 further provide a link 12, which may beslipped over the base of the yoke before the same is interlocked withthe yoke below it. The link 12 is adapted to embrace the said yoke andrest upon the inturned hooked extremities of the yoke below it, andextend beyond the wall through the opening 10 in said bracket 9 andcontain the tongue 11.

Having fully described my invention, I claim:

1.
